Specification of Letters Patent. Patentod Sept. '7, 1909.

Application filed October 2, 1907:. Serial No. 395,584.

, To all whom it may concern:

lle it known that I, FRANK B. DUNN, a culzen of the United States,residing at (lonneaut, in the county of Ashta'bula and State of Ohio,have invented certain new q and useful Improvements in Mechanism for-Cutting lVire-(Jut Brick; and I do hereby declare the following to be afull, clear, and

exact descriptioinof the invention, such as 0 will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accom anying drawings, and to the letters of re erencemarked thereon, forming-part of this specification.

My invention relates to wire-cut brick, and has for its obj ect theproduction of wirecut brick having wire-cut ribs on one side andcorresponding wire-cut depressions on the other, and mechanism forcutting such ln'lck. v 4

vAs iswell understood in the art, wire-cut brick are produced by passingone or more wires through a column of clay resting on a platen havingslots therethrough for the passage of the wires, as the column of clayis forced out thereon from theclay mixer through a suitable die. Toaccomplish the desired result I make the slots in the platen virregularso as to varythe line, of the'travel of the wires therethrough andthrough the column of clay, from a direct line to an irregular line oftravel, thereby leaving wirecut grooveson one side and wirecut ribs onthe opposite side of e ch brick out. A convenient mechanism forproducing this result is hereinafter fully set forth and described,

and illustrated in the accompanying draw-v ings in which Figure 1 1s atransversexview in section of an ordinary rotary brick cutter, embodyinga form of mechanism for cutting brick made 1n accordance wlth mymventmn.Fig. 21s a side view ofa section ofan lmproved platen, suitable forcarrying out my invention, looking in the I in Fig. 1. Fig. 3 is a topor plan view of y direction of the arrow a section of said improvedplaten looking in the direction of the arrow y in Fig. 1. Fig.

4 is a perspective view of a wlre-cutbrick made in accordance with myinvention.

' The brick cutting machine illustrated in the accompanying drawings isof vthe ordinary type, in which end rings are "rotated insupportingframes B and drlven by ears ame B having a central ring 'Dupon which rings D are mounted and from which cut-ting wires E extendtobars A between the rings A. The platen-sections F upon which the columnof clay from the v the of the brick machine travels-through the cutter,are secured to,,th e,central-bearing D by means of upwardlyiextendingarm F, between which the rings D"'rotate. operation, the cuttingmechanism and platen travel in unison with the travel of the clay columnissuing machine during the cutting operation, and is provided with theusual mechanism lot shown) operating periodically to automatically movesaid mechanism in the opposite direction from that of the travel of theclay.

column preparatory to making another out, all which features are commonin brick cutting machines. The novel features which I have added'to thismechanism and by means whereof I am enabled to produce wire-cutbrickwith wire-cut ribs on one side and wire-cut grooves on the oppositeside, consist substantially in'making the slots f in the platen withcurved offsets f on one side of the grooves f, and opposite said oifsetsf, I preferably pivot rollers G,.so that as the cutting-wires E passthrough the slots 7 they contact with the rollers G and are defiectedthereby into the offsets f.

To guide the cutting-wires E at the upper edge of the brick, I secure,slightly above'the brick,to the armsF which support the pl atensectionsF, guide-sections H, parallel to and corresponding in width to theplaten-sections F, and the slots h between these guide-sections II arealso provided with offsets h, and with rollersG opposite said offsets,so that as the"cutting-wires E pass. the rollers G they are deflectedinto .the offsets hso as toproduce grooves 2' of equal depth from edgeto' edge of the brick I on one. sid'e,.and ribs 11 of equal height fromedge to edge of said brick on the opposite side thereof, thus producinga wire-cut. brick with transverse wirecut ribs on one side and wire-cuttransverse grooves on the other. I s v Herei before-I havefd'scribed asuitable form of mechanism for producing wire-cut :brick with ribs onone sidefand grooves on the other. It is' obvious however that manyforms of mechanism may-be devised for producing wire-cut brick withtransverse ribs and grooves thereon without departing from. v

the spirit of my invention. 'Iherefore hav- In I from the die of thebrick ing described suitable mechanism for producing wire-cut brickhaving transverse grooves in one side and transverse ribs on the other,what I claim as new and desire to secure by Letters-Patent is:

l. The combination in a machine for wirecutting brick from acontinuously moving column of clay-comprised substantially of mechanismoperating'one or more tensioned cutting wires, a transversely slottedplaten upon whlch the clay-column is supported and through which t: 1etensioned cutting wires pass traveling 1 unison therewith and with theclay column during the cutting operation, and means in said platen slotsfor deflecting the cutting wires as they pass through said slots and acolumn of clay supported on said platen, substantially as set torth. v

2., T he combination in a machlne for wirecu'tting brick from acontinuously moving column of clay comprised substantially of mechanismautomatically operating cutting wires, a transversely slotted platenmounted in the path traversed by said cutting wires and travelingin-nnison therewith and with the cla column during the cuttingoperation, and 0 sets in said platen slots-for deflecting the cuttingwires from a straight line of travel during their passage through saidslots and a clay column' supported on said platen, {substantially as setforth. 3. The combination in 'a machine for wire-.' cutting bricklfrcolumn of clay comprised subsantially ofautomatica l l operated cutting.wires, a

transversely slotted platen mounted in the path traversed by saidcutting; wires and travelin in unison therewith and with the column fclay during 'the cutting operat on, atransversely slotted guide abovethe trans-v versely slotted platen, and ofi'setsin the slots in saidplaten and in the slots in said guide,

whereby the cutting wires are equally dea continuously moving;

flected from a direct line of travel through said slots during thecutting operation both at the upper and lower edges of the brickb'eingcut, substantially as set fortlil 4.
